About Us

Founded in 2011, OncoStem Diagnostics aims to develop innovative multi-marker prognostic tests to carefully personalize treatments for breast cancer patients.

Cancer is a complex disease and, at OncoStem, we develop tests that help identify patterns of recurrence. An understanding of these patterns ensures that patients receive therapies and treatments tailor-made to their condition.

Our approach to cancer research and diagnosis involves integrating the molecular signature of the disease with clinicopathological parameters. This time-tested methodology allows us to accurately predict the course of the cancer.

Our expertise in tumor biology assists physicians in developing optimal therapeutic plans for patients. We utilize gold-standard protein or gene expression techniques in our assays and combine them with a deep learning approach to further our understanding of cancer.

CanAssist-Breast, a test created by OncoStem, identifies the risk of breast cancer recurrence. Every test developed in our labs has been designed with the intention aiding targeted therapies.

OncoStem is currently working on similar tests for oral, lung, and colorectal cancer. Research is underway towards identifying and characterizing novel drug targets for breast and oral cancer.
